Cold-pressing production board and preparation method thereof

The invention relates to the technical field of wood processing, in particular to a cold-pressing production board and a preparation method thereof. The cold-pressing production board is prepared fromthe following raw materials in percentage by weight: 50-60 parts of crop straw, 5-10 parts of gypsum powder, 30-50 parts of magnesium oxide powder, 2-5 parts of adhesive, 1-5 parts of waterproof agent and 1-3 parts of fire retardant and comprises auxiliary materials of 0.1-0.5 part of sulfuric acid solution, 0.05-0.08 part of sodium hydroxide solution, 1-5 parts of rubber powder and 0.5-1 part oftraditional Chinese medicine powder. The cold-pressing production board and the preparation method thereof effectively solves the contradiction between the policy of limited wood cutting and the supply and demand of wood, and solves the problem of environmental pollution caused by burning straws by farmers. As traditional Chinese medicine for depositing harmful substances is added, the formaldehyde volatilization of artif
